- Having thus described the invention, what is claimed as new, is

A tire tread comprising a tread body provided With a pair of eircumferentially disposed parallel ribs extending entirely around the tire in spaced relation .to tbe Center line thereof, spaced ribs connecting the pair of ribs to divide the space between said pair into a series of substantially square pockets, short stout ribs in staggered rel lation oneaeli side of said `pair ofv ribs, the

ribs on one k.side beingvalined with every other transverse rib, the short stout ribs on theremaining` sidebeing alined With the remaining. transverse ribs, and beads each connected to one of said short stout ribs and having their ends in spaced relation to provide open-1nouthed pockets, the outer sides of all of said heads being straight and in A alinenient and the under sides of all of said heads being curved from the straight portion whereby to provide a ground gripping side and walls for tlie pocket mouths adapted to readily release material held in said pockets.

ln testimony whereof I alix my signature in presence of two Witnesses.
